Install n8n on Oracle Ubuntu VPS (Docker, Auto-Start, Persistent)

---

🔹 Step 1: Update and Install Docker

sudo apt update && sudo apt install -y docker.io
sudo systemctl enable docker --now

🔸 This ensures Docker is installed and will start on every reboot.

---

🔹 Step 2: Create a Docker Volume and Run n8n Persistently

Run this single command to:

• Create a named volume for persistent n8n data

• Start n8n in the background

• Ensure n8n auto-starts on boot

sudo docker run -d --name n8n \
  --restart=always \
  -p 5678:5678 \
  -v n8n_data:/home/node/.n8n \
  -e N8N_HOST=0.0.0.0 \
  -e N8N_PORT=5678 \
  -e WEBHOOK_URL=https://your_domain_or_ip_address/ \
  -e VUE_APP_URL_BASE_API=https://your_domain_or_ip_address/ \
  docker.n8n.io/n8nio/n8n

---

🔹 Step 3: Access n8n in Your Browser

Once the container is running, open:

http://<your_server_public_ip>:5678

You’ll see the n8n interface. You can now start creating workflows.

💡 Make sure port 5678 is allowed in your Oracle Cloud VCN security list or Network Security Group.

🔹 Step 4 (Optional): Disable Secure Cookie (for testing only)

If you get a browser warning like:

“Your n8n server is configured to use a secure cookie…”

You can fix it by disabling secure cookies (not recommended for production):

docker rm -f n8n && \
docker run -d --name n8n \
  --restart=always \
  -e N8N_SECURE_COOKIE=false \
  -p 5678:5678 \
  -e WEBHOOK_URL=https://your_domain_or_ip_address/ \
  -e VUE_APP_URL_BASE_API=https://your_domain_or_ip_address/ \
  -v n8n_data:/home/node/.n8n \
  docker.n8n.io/n8nio/n8n

---

🔹 Step 5 (Optional): Set Up with a Domain and HTTPS

For a production setup, you should:

• Point a domain/subdomain to your VPS

• Use Cloudflare Tunnel, NGINX, or Traefik for HTTPS

• Configure n8n with environment variables like WEBHOOK_URL, VUE_APP_URL_BASE_API, etc.
